The bag creates a tiny pressure cooker. Steam circulates inside, cooking the bird evenly. No basting required. None. That’s hours of freedom you get back.
But here’s the quirky fact: the bag must have a slit. Cut a few small holes in the top. Otherwise, it inflates like a balloon and might explode. Your kitchen isn’t a science experiment (unless you want it to be).
Also, don’t forget the flour. Shake a tablespoon of flour inside the bag before adding the turkey. It prevents the bag from bursting and helps thicken the juices into gravy. Science and dinner in one move.
Size Matters (The Turkey, Not You)
A small bird (8-10 lbs) cooks fast. 1 hour 45 minutes to 2 hours 15 minutes. That’s shorter than a movie. A medium turkey (12-16 lbs) needs 2.5 to 3 hours. Please, do not wander off.
Extra-large turkeys (18-22 lbs) are beasts. They need 3.5 to 4 hours. But here’s a pro tip: let it rest in the bag for 15 minutes after cooking. The residual heat finishes the job without overcooking.
What about the stuffing? If you stuff the bird, add 15 minutes to the total time. The stuffing must hit 165°F inside. Or just skip stuffing—cook it in a dish. Less stress, more crispy corners.
